Among the most remarkable of the flying reptiles of the island was the small, bizarre, fairylike feather devil from the jungles of Skull Island. Totally unrelated to any of the other flying reptiles on the island, Feather devils have developed attenuated scales analogous to birds feathers. These lay flat along the reptile's sides while climbing and hunting, but flicked open to allow the little insect eater to flit from tree to tree in pursuit of prey.
Of all the gliding reptiles, they are the most agile in the air, changing direction in midflight to chase insects or avoid a larger predator (like a Wicked Weaver) with graceful ease.
Feather devils can bark, similar to many species of gecko, and do so to communicate with each other and could easily be heard in the dark of the jungle. Males bark to proclaim ownership of territory or to impress potential mates. At certain times of year the forest rings with the froglike croaks of hundreds of the tiny lizards laying claim to their particular stretches of branch.
- The feather-devil is quite similar to the dinosaur Microraptor.
